f This invention particularly pertainsto "a" metal lath. V a

`A411 object of the invention is to provide a wire latli having tliequalities ofstrength,

flexibility,`and lightness,' and Which is adapt ed to be manufactured at small cost, which maybe easily and quickly applied, and Which t `is adaptedto be employed either as an exte- "rior orinterior'lath.

The netting may be also attached to the backing sheet by means of stitching shown in Fig. 4; a cord 15 being passedvback and Vforth through the sheet 12 and engaged with the projections 9 on the nt ting. .Another forni of attachment cons s of wires or threads 16 `extendingjtranw sely of the netting and arranged in the lll-shaped projections 9 as shown in l 1 5, which wires or cords are fastened through the sheet 1Q by staples or stitching 17. ln any event the Wire netting will be positioned in positive spaced relation to the backing sheet at all times and the method of fastening` the netting to the backing sheet Will render the backing sheet substantially imperforatc. Vi`his Will insure that the strength of the backing sheet will be preserved and that it will be an effective barrier lto mortar or moisture which would through a perforate backing sheet.

Jl/Vhen'desired the sheet with the Wirenetting affixed thereto may be dipped in a liquid such as asphaltum so as to coat the backing sheet and the netting with a non-absorptive mater-iat This material will also close any sniall perforations formed through the backing sheet incident to the stitching or fastening operation, if such perforations should accidently occur, thereby rendering the assembled lath structure fully Waterproof. rEhe coating material indicated at 18 is adhesive in character and is applied in such thickness as to form a bond for a fragmentary material 19 whichV is applie'dto the coating While the lat- -ter soft. T he fragmentary material 19 may be of granular character suchas calcined diatomaceous earth, or may consist of a-suitable fibrous material or may` comprise both a granular and a fibrous material. This fragmentary matter being highly absorptive of mois- Whereby the plaster Will be anchored to the surface of the backing sheet as Well as held and reinforcedby the nett-ing which is coml pletely embedded within it.

rllhe sheet lath thus formed may be secured to studding A21 or other suitable frame-Work by nails :22 which are driven thru the bz, elring sheet alongside of the projections 9v and i clinched over the projections as shown in Fig.

1. The backing sheet thus affords means 'whereby the -lath may be mounted te span open spaces it aifords'a backing for Athe plaster coating20; the backing sheet being tied throughoutat comparatively7 close' intervals to the .vire'netting so as to inhibitits being pressed away from the latter. The adhecoating in which the Wire netting and the backing are'embedded serves `to securely re;-

tain the backing sheet Vand nettingin their connected,condition. The lath is of such rigidity that it may be carried on a 4framework of spaced supports but is of such flexible character that it may be bent to form curved surfaces such as the curved faces of arches, coves and rounded corners, and is admirably suited as a lath for round columns and curved Walls.

By forming the Wire netting as here set forth the major portion of the netting Will be positively held in spaced relation to the backing at all times so that when plaster is applied 'hereto a substantial body of plaster will extend between the netting and its backing surface as shown in-Figs. 1 and 2, completely embedding the same and thus providing a strong support and reinforcement for the plaster. By alfixing the Wire netting to the backing sheet a unitary structure is formed whereby the backing sheet andv Wire maybe applied to a framework or surface at one operation.
